core/html/parser/XSSAuditor.cpp in the XSS auditor in Blink, as used in Google Chrome before 33.0.1750.117, inserts the about:blank URL during certain blocking of FORM elements within HTTP requests, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via unspecified vectors.

Security readout for executives and security teams

CVE-2013-6657 is an old browser flaw in Blink’s XSS Auditor used by Google Chrome before 33.0.1750.117. In certain form-blocking cases, it could insert about:blank in a way that bypassed the Same Origin Policy, potentially exposing sensitive information to a remote attacker. Exposure is most plausible on legacy Google Chrome or Chromium-derived packages predating Chrome 33.0.1750.117, including old distribution builds referenced by Debian and openSUSE advisories. Current exposure cannot be inferred from the bundle without local asset data. Treat as a legacy exposure cleanup item unless asset inventory shows affected browsers still in use. The business risk is sensitive information exposure through browser origin-policy bypass, but no active exploitation is cited in the provided sources. Mitigation focus: Upgrade Chrome to 33.0.1750.117 or later where applicable.; Apply vendor-fixed Chromium or browser packages from Debian or openSUSE advisories.; Identify unsupported legacy browsers and remove them from managed endpoints..
